> You have to write a bit of minor scaffolding:
> private MyObject _object;
> void onPrepare() {
>   if (_object == null)
>     _object = new MyObject();
> }
> Seems like the BeanEditForm could do this on its own: check for null, create a new instance, update the parameter at the end of the render or form submission.
> Obviously, this is predicated on the type being a JavaBean with a no-args constructor, and not an interface or abstract class, or anything else more complicated.
